Abstract
1430054 D.C.-D.C. converters PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 June 1974 [29 June 1973] 28315/74 Heading H2F In a D.C.-D.C. converter of the type in which at least one current interrupter A2 is coupled via a transformer to a rectifier D3, providing D.C. output, an asymmetrically conductive circuit is included on the primary side of the transformer for reducing the primary voltage when the current is interrupted. The invention also includes either: (a) a circuit S11 for inhibiting closure of the current interrupter A2 in response to the presence of the potential across the secondary winding in the reverse direction of the rectifier D3; or (b) a charge storage element C6 (Fig. 4) coupled to the primary T6 via a pair of current interrupters A5, A6, in which the primary voltage is controlled by means of a pair of cross-coupled asymmetrically conductive devices D11, D12. As described, when transistor A2 is conductive, rectifier D3 provides D.C. output at K7, K8. When A2 is cut off, diode D13 turns on transistor A3 which dissipates the energy in the primary T4. Diode D5 also becomes conductive, turning on transistor A4 which turns on an inhibiting circuit S11 which inhibits further triggering of A2 until the transformer yoke becomes sufficiently demagnetized and thus prevents core saturation. Free-wheeling diode D4 maintains low current in inductor L1. In Fig. 4 the D.C. input is derived by rectifying A.C. at K9, K10 by means of a diode bridge D6 ... D9 which charges capacitor C6. Transistors A5, A6 are turned on in synchronism to provide the power pulse whilst diodes D11, D12 become conductive when A5, A6 are turned off, to return surplus energy to C6. The secondary circuit is the same as in Fig. 3. Thyristor TH is turned on by the voltage across winding T7 so as to short circuit resistor R9 when the circuit is operating correctly. Reference is also made to the primary and secondary currents providing cancellation of the core magnetization.
